CARBU RETO R.

SPECIFICATION forming part of Letters Patent No. 409,570, dated August 20, 1889. Application filed April 12, 1889. serial No. 307,065. (No model.)

To (all whom it may concern.-

Be it known that I, JOSEPH ELDER, of Peoria, in the county of Peoria and State of Illinois, have invent-ed certain Improvements in Carburetors, of which the following is a specification.

This invention relates to an apparatus for carbureting air or gas for illuminating and heating purposes; and it consists in a body provided with peculiarly-arranged chambers to contain a hydrocarbon oil and secure the contact of the air or gas therewith.

In the accompanying drawings, Figure 1 is a longitudinal vertical section of my carburetor. Figs. 2 and 3 are sections of the same on the line w 00, looking in opposite directions.

Referring to the drawings, A represents a closed casing, of sheet metal or other suitable material, preferably of an oblong rectangular form. This body is divided by the horizontal partitions a and a into three chambers 19, c, and d. An inlet-pipe 6 leads downward through the top of the body directly into the bottom chamber d, where it terminates at the top of the chamber in a cross-pipe 9, having a narrow slit or orifice. At the opposite end of the casing a pipe 9 leads from the top of the bottom chamber d upward to the top of respective pipes.

the chamber 0. This pipe terminates at each end in a cross-pipe having a narrow slit therein. At the opposite end from the pipe 9 a pipe 72, having a slitted cross-arm in the top of chamber 0, leads into the top chamber b. This top chamber is provided at the opposite end with an outlet-pipe i. The chambers c and d are provided at one end with filling-spouts f.

In operating the apparatus the lower two chambers are filled with naphtha or similar material to a point near the lower ends of the The air or gas entering the pipe 6 descends into the bottom chamber (Z, and is distributed and delivered into the top of this chamber in a thin sheet or film above the surface of the naphtha, over which it flows to the opposite end of the chamber, where it ascends through the pipe g into the top of the chamber 0, where it is again diffused or distributed and compelled to pass over the surface of the naphtha to the pipe h at the opposite end, where it ascends into the chamber 1), and passing therethrough escapes atz'. The top chamber 1) may be filled with cot-ton or other absorbent material to prevent excessive saturation of the gas or air. The air or gas charged with the hydrocarbon vapor is heavier than air and naturally. sinks. Owing to this fact it is advantageous to deliver the air and gas into the bottom chamber first and to compel their ascent through the chambers above. Being delivered under pressure, the air or gas has considerable velocity and travels across the upper part of the chambers from the inlet to the outlet openings with considerable rapidity.

The delivery of the air or gas first into the base of the apparatus and thence upward toward the point of deliveryis advantageous, in that the air is thus retarded sufliciently to secure a thorough combination with the hydrocarbon vapor, while at the same time any excess of vapor which may be momentarily suspended in the air is precipitated within the apparatus instead of being carried over into the delivery pipe.

Having thus described my invention, what I claim is 1. Ina carburetor, the body divided by horizontal partitions into distinct chambers, in combination with the pipe leading into the top of the bottom chamber, the pipe leading from the top of the bottom chamber to the top of the one above and the outlet-pipe h, each of said pipes terminating in a cross pipe with a narrow horizontal slit therein, substantially as described and shown.

2. In a carburetor, a chamber d nearly filled with a hydrocarbon, in combination with an inlet-pipe presenting a narrow slit across one end of the chamber above the liquid, and a similar slitted outlet-pipe at the opposite end of the chamber, whereby air or gas is directed in a thin sheet across the top of the chamber.

In testimony whereof I hereunto set my hand, this 9th day of March, 1889, in the presence of two attesting witnesses.

JOSEPH ELDER.
